Building the Pitts Wings

S1S vs. S1C wing design

Click Here Brent is working on the aileron area, you can see the clamps
holding the front spar doubler
plate.

You can also see the metal trailing edge. In the background is
a recently restored Pitts that the Smith's just completed. The new
wing is for an S1-S Pitts which has a symmetrical wing, the Pitts in the
background is an S1-C which does not have a symmetrical wing. A symmetrical
wing allows the plane to fly better inverted however it increases the amount
of drag in cruise flight and reduces the top speed and cruise range of
the aircraft. But, in an aerobatic airplane top and cruise range
are of the least importance, the Aerobatic ability of the aircraft is what
is needed. It's interesting to watch these two types of aircraft
flying inverted. The S1C has a much higher angle of attach in the
inverted position than the S1S.
